Installation
Install Firmware On Cisco Unified Communication Manager
Before using Cisco Unified IP Phone Firmware Release 9.4(2)SR3 with Cisco Unified Communications Manager, you must install the latest firmware on all Cisco Unified Communications Manager servers in the cluster.
The Cisco Unified IP Phone 8941 and 8945 support the “secure by default” feature. All phones with Release 9.3(1) or later require that Cisco Unified Communications Manager has Device Pack 8.0.3(24049), 8.5.1(14070), 8.6.2(22030) or later installed. If the correct device pack is not installed first, the phones cannot successfully register to Cisco Unified Communications Manager.
Note
Release 9.4(2)SR3 can only be upgraded from 9.3(4) and later. Releases prior to 9.3(4) have to be upgraded to 9.3(4) first.
Note
Step 1 Go to the following URL:
http://www.cisco.com/cisco/software/navigator.html?mdfid=268437892&flowid=5293 Step 2 Choose your phone model.
Step 3 Choose one of the following firmware types:

Limitations and Restrictions
Phone Behavior During Times of Network Congestion
Anything that degrades network performance can affect Cisco IP Phone voice and video quality, and in some cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following activities:
• Administrative tasks, such as an internal port scan or security scan
• Attacks that occur on your network, such as a Denial of Service attack
On-Hook Transfer Limitation in SIP Phones
When the Cisco Unified Communications Manager Transfer On-Hook Enabled field is enabled, users might report a problem with direct call transfer in SIP phones. If the user transfers the call and immediately goes on hook before they hear the ring signal, the call may drop instead of being transferred.
The user needs to hear the ring signal so that they can be sure that the call is being routed.
Language Limitation
There is no localized Keyboard Alpha-Numeric Text Entry (KATE) support for the following Asian locales:
• Chinese (China)
• Chinese (Hong Kong)
• Chinese (Taiwan)
• Japanese (Japan)
• Korean (Korea Republic)
The default English (United States) KATE is presented to the user instead.
For example, the phone screen will show text in Korean, but the 2 key on the keypad willdisplay a b c 2 A B C.

Unified Communications Manager Endpoints Locale Installer
By default, Cisco IP Phones are set up for the English (United States) locale. To use the Cisco IP Phones in other locales, you must install the locale-specific version of the Unified Communications Manager Endpoints Locale Installer on every Cisco Unified Communications Manager server in the cluster. The Locale Installer installs the latest translated text for the phone user interface and country-specific phone tones on your system so that they are available for the Cisco IP Phones.
To access the Locale Installer required for a release, accesshttp://software.cisco.com/download/
navigator.html?mdfid=286037605&flowid=46245, navigate to your phone model, and select the Unified Communications Manager Endpoints Locale Installer link.
For more information, see the documentation for your particular Cisco Unified Communications Manager release.
The latest Locale Installer may not be immediately available; continue to check the website for updates.

Cisco Unified Communication Manager Public Keys
To improve software integrity protection, new public keys are used to sign cop files for Cisco Unified Communications Manager Release 10.0.1 and later. These cop files have “k3” in their name. To install a k3 cop file on a pre-10.0.1 Cisco Unified Communications Manager, consult the README for the
ciscocm.version3-keys.cop.sgn to determine if this additional cop file must first be installed on your specific Cisco Unified Communications Manager version. If these keys are not present and are required, you will see the error “The selected file is not valid” when you try to install the software package.

collaboration-endpoints/unified-ip-phone-7900-series/116684-technote-ipphone-00.html.
Cisco IP Phone Documentation Updates on Cisco Unified Communications Manager
The Cisco Unified Communications Manager Self Care Portal (Release 10.0 and later) and User Options web pages (Release 9.1 and earlier) provide links to the IP Phone user guides in PDF format. These user guides are stored on the Cisco Unified Communications Manager and are up to date when the Cisco Unified Communications Manager release is first made available to customers.
After a Cisco Unified Communications Manager release, subsequent updates to the user guides appear only on the Cisco website. The phone firmware release notes contain the applicable documentation URLs. In the web pages, updated documents display “Updated” beside the document link.
The Cisco Unified Communications Manager Device Packages and the Unified Communications Manager Endpoints Locale Installer do not update the English user guides on the Cisco Unified Communications Manager.
Note
Administrators and users should check the Cisco website for updated user guides and download the PDF files.
Administrators can also make the files available to the users on their company website.
Administrators may want to bookmark the web pages for the phone models that are deployed in their company and send these URLs to their users.
